Comparison of both is
Highway pavement
- Cost is low.
- Less toughness compare to airfield.
- Design load is less.
- Less hardness compare to airfield.
- Compare to airfield, less construction cost and design cost.
- Length of Highway payment is very high.
Airfield pavement
- Cost is high.
- High toughness need.
- Design load is very High
- Need higher resistant to wear and tear due to aircraft trust.
- Design cost and material cost is high due to rigid specifications and high level of construction practice.
- Length of airfield pavement is less compare to Highway pavement.

The maximum degree of curve or smallest radius for a railroad is 3 degrees on a new main line track with a maximum grade of 1% compensated at 0.04% per degree of curve; therefore a grade in a 3 degree curve would actually be 0.88%. For a highway it depends on what kind, where, typical traffic, speedRead more
The maximum degree of curve or smallest radius for a railroad is 3 degrees on a new main line track with a maximum grade of 1% compensated at 0.04% per degree of curve; therefore a grade in a 3 degree curve would actually be 0.88%. For a highway it depends on what kind, where, typical traffic, speed limits, etc. Degree of curve is the angle between the radii of a curve of a 100 foot chord which is chord definition. Highway departments usually use Degree of Curve as the angle between the radii of a curve of an arc of 100 feet. For curves 3 degrees or under, the difference between the definitions staked on the ground is inconsequential.
